If ticks is always related to samples by a constant factor, and everything
must convert between the two ehy not just represent timestamps as samples
and be done with it.
In my discussion, I always meant ticks in relation to musical time, which is
to say - NOT related to sample time in any direct way.
I think we all agree that some constant, monotonic, absolute value is the
fundamental timestamp. Samples are used everywhere, and the host already
provides knowledge of samples/sec.
More from me as I work through the list of messages to which I must respond.
